inadequacy of water power as a substitute for oil and coal. Those who 
think otherwise usually consider the question from the standpoint of 
factory power only, leaving out of consideration the enormous quantities of 
energy required to heat our homes, and to supply heat for such processes 
as ore smelting, cement manufacture, brick, tile and glass making, and 
thousands of others. To equal one ton of coal per month for heating 
purposes one would require the entire output of a fourteen horse-power 
plant, running twenty-four hours per day thirty days per month. If there 
are five hundred thousand families in Indiana and if each family con- 
sumes an average of two tons of coal per month during the winter season, 
the consumption is the heat equivalent of fourteen million horsepower. 
Remember, too, that Indiana is not a very populous State and that its 
climate is not severe. 
Professor Soddy states the facts in his little volume on ‘Matter and 
Energy” when he says that “the age in which we live, the age of coal, 
draws its vivifying stream from a dwindling puddle left between the com- 
ings and goings of the cosmical tide.” 
We are to “witness a race, a race between science on the one hand and 
the depletion of Our natural resources on the other hand.” This race will 
be run chiefly by pure science, not by applied science. Engineers and in- 
yentors make their reputations and their fortunes by devising new and im- 
proved methods of using our natural resources; they are not concerned with 
the atom, the latest and the greatest energy reservoir discovered by man. 
We must look to such scientists as Becquerel, Curie, Rutherford, Ramsay. 
We must look to the humble, overworked, underpaid scholar toiling away in 
his laboratory. If he fails us, darkness comes.
